Cores
Cores	6 Performance-cores and 4 Efficient-cores, with Hyper-Threading; codename Raptor Lake	Broadwell-E; 10 cores with Hyper-Threading. The unlocked multiplier is confirmed by the exact-model reviews.
Clocks
Clocks	P-core base 2.5 GHz, max turbo 4.7 GHz; E-core base 1.8 GHz, max turbo 3.5 GHz	Turbo Boost Max 3.0 up to 4.00 GHz on the preferred core; ordinary Turbo Boost 2.0 up to 3.50 GHz. The main boost field uses Intel’s highest published frequency. May availability follows Tom’s Hardware’s 31 May 2016 report, attributing immediate sale of all four models to Intel. Intel’s family record is dated 30 May and ARK gives Q2 2016; the announcement day is not treated as an exact first-sale day.
